I'd like to thank you all very much for your responses! :)
Installing the older version v4r2 as per your translations appears to have worked, though I first had problems with it conflicting with my earlier attempts at getting v5r3 to work (I really need to learn more about Linux and the deb/rpm package management systems). In any case, I can now execute: # /emul/linux/opt/tivoli/tsm/client/ba/bin/dsmc ANS1035S Options file '/opt/tivoli/tsm/client/ba/bin/dsm.sys' not found This error message is normal: That's what it says when its configuration file isn't there. It could take some time till I manage to fully configure and test this as I need to get an additional account (for backing up the OpenBSD server) from the maintainers of the central Tivoli/TSM backup server. That said, I fully intend to follow-up once I've had a chance to find out whether it's definitely working or not. Again, many thanks for your help! :) --ropers
